Ridley is a totally different argument because his wings are big and his limbs are big and he has a huge tail and he is generally muscular but not filled out. Don't try to compare characters that make sense with one that doesn't (i.e. Ridley).
You know how you make something not big? *RESCALE THE CHARACTER*. I'm sorry, but can you think a bit harder? This really is not complicated whatsoever. You are literally sitting here and refusing to acknowledge things that are in no way obfuscated or hard to understand/figure out.
1) Big wings can and will be folded in. That is literally how wings work. They are going to be folded in when they are not in use. *THAT IS HOW WINGS WORK*.
2) Muscular but not filled out? What are you even saying anymore? I can't tell if you are actually talking about his posture, when OTHER characters have had bizarre un-full posture, or if you are trying to sound like you have no idea what you are talking about. Either way, sorry Greninja and Wolf. You don't stand upright, so you both have to go.
3) Big limbs happen to big characters. No big limbs? Sorry Bowser. Sorry Ganondorf. Sorry DK. Sorry Dedede. You're gone. You aren't allowed to have limbs proportional to your large bodies.
4) A huge tail? His tail is LONG, THIN, and is generally rope-like in nature. It could easily be curled up close to the back when not in use, and stabbed outward with the sharp end first. Charizard's tail is large, thick, and not nearly as maneuverable. So of course it would be different. If anything, it would work BETTER for Ridley than it did for Charizard.
5) "Don't try to compare characters that make sense with one that doesn't (i.e. Ridley)."
So don't refute your terribly constructed argument with obvious facts? That's not allowed? And to reinforce that, obviously all characters that are in the game EVEN THOUGH they break all of the rules you have made here "make sense" and one that hasn't been in a game yet but can easily be worked out DESPITE all of your bizarre fabricated restrictions "doesn't make sense"?
That's game, set, and match. Pack up and head out. You can come back when you're actually going to participate in a serious, thought-out discussion.
